OIL-CAN.

Specification of Letters Patent.

Patented Apr. 11, 1911.

Application filed September 24, 1910. Serial No. 583,631.

T o all whom it may concern:

Be it known that I, Jarras T. SMALLwooD, a citizen of the United States,residing at Sedalia, in the county ot Pettis and State of Missouri, haveinvented new and useful Improvements in Oil-Cans, of which the tollowingis a specification.

This invention relates to oil cans and particularly to attachments forthe body of the ordinary oil can.

The object of the invention is the provision of a pumping attachmentwhich may be inserted into the ordinary oil can when the latter becomesinoperative by reason of fre-- quent dents caused by mishandling or'from any other reason.

A still further object of the invention is the provision of a device ofthis character which may be applied to the ordinary oil can and renderedinoperative so that the oil will flow out of the same by pumping thediaphragm in the ordinary manner.

A still further object of the invention is the provision of a pumpingattachment for oil can which enables the user thereof to oil parts ofmachinery which are situated overhead and in such positions as toprevent the inverting oit the can.

Still further objects of the invention will appear as the followingspecific description is read in connection with the accompanyingdrawings which form a part of this specification, and in which:

Figure 1 is an elevation, with parts in section and other parts brokenaway. Fig. 2 is a similar view of the attachment removed from the can.Fig. 3 is a similar view showing the attachment in locked position, andFig. 4 is a longitudinal sectional view through the attachment, the canbeing shown in dotted lines.

Referring more especially to the drawings, 1 represents the can which isprovided with the usual diaphragm bottom 2 and the threaded aperture inits upper end to receive the spout. The attachment comprises outer andinner cylinders 3 and 4, the former of which comprises a pump cylinderand is provided on its upper exterior portion with a thread 5 adapted toenter the aperture in the can and is also provided with a milled disk 5by which the device may be threaded into the cam. The lower end of theoutside cylinder 3 is closed by an apertured disk 6 which forms a valveseat for the check valve 7. This check valve is limited in its upwardmovement or away from its seat by a rod 8 which passes diamctricallyacross the cylinder' a short distance above the aperture and is securedin the walls oi? the cylinder.

The inner cylinder has its upper end threaded to receive the spout 9which has a collar 9 upon its lower end forming a finger hold by whichthe device may be manipulated, the hold being engaged on either side bythe tore and middle lingers. The lower end or the inner cylinder isclosed by an apertured disk 10 in which is seated a valve 11 which movesin the same direction as the valve 7 and is adapted to hold the oilwithin the inner cylinder after being forced thereinto by the downwardaction of said cylinder.

Passing across the inner cylinder 4 and projecting through one sidethereof is a retaining pin 12 which operates in the slots 13 and 14, theslot 14 extending longitudinally of the cylinder and the slot 13extending at right angles from the head of the slot 14. The slot 14 isextended slight-ly beyond its juncture with the slot 13 so as to form arecess 14 in which the pin is seated to prevent accidental displacement.A spring 15 arranged between the cylinders is adapted to normally keepthe pin in the recess 14 and the inner cylinder in extended position thepin 12 and end walls of the slot 14 serve to limit the movement of theinner cylinder or plunger.

Suitable apertures 16 and 17 are formed in the inner and outer cylinderswhich when the device is in normal position are out of register, butwhich are adapted to register when the pin is in the lateral slot 13. Inthis position the cylinder cannot work as a pump and the oil can is usedin the ordinary manner by pressure upon the diaphragm bottom 2, the oilpassing into the spout through the apertures 16 and 17, uninterrupted bythe valves.

In order to form a tight joint between the inner and outer cylinders, Isecure in the milled disk 5 a suitable gasket 18 in any suitable manner.

Having thus described the invention, what is claimed is- 1. Thecombination with an oil can, of a pump cylinder secured therein, ahollow plunger mounted to reciprocate in the cylinder, means fornormally keeping the plunger projected, means for locking the plunger ininoperative position, and a spout carried by the plunger.

combination with an oil can, of a. valved pump cylinder threadedtherein, a valved hollow plunger reciprocating in said cylinder, meansto limit the movement of said plunger, said cylinder and plunger havingapertures which are out of register when the plunger is in operativeposition, and means to bring the apertures into register and to rendersaid plunger inoperative,

4. ln a device of the class deseribed, the combination with an oil can,of a valved pump cylinder' mounted therein, said cylinder having alongitudinal Ielet and a lateral` slot eonn'nunicating therewith, ahollow pump plunger mounted to reciprocate in the cylinder, a pinadapted to extend outwardly from the plunger to enter the slots andlimit the movement of the plunger, said cylinder and pl unger havingapertures therein which are adapted to register when the pin is in thelateral slot and to be out of register when it is in the longitudinalslot, a spout carried by the plunger, and means carried by the spout foroperating the plunger.

In testimony whereof I atlix my signature in presence of two witnesses.

JAMES T. SMALL'WOOD.
